FINISH-REMOVEB.

We Drawing.

To all whom it may concern Be it known that I, CARLETON Enn s, a citizen of the l niterl States, and resident of Larchmont, in the county of Westchester and State of New York, have made certain new and useful Inventions Relating to Finish-Removers, of which the following is a specification.-

This invention relates to finish removers and relates especially to removers of a. substantially non-inflammable character in which the volatile inflammable ingredients are so combined with non-inflammable bodies but suppresses the inflaii'ima-bility of many or solvents, such chlorinated derivatives of acetylene as to be nnobjectionable under ordinary conditions of use.

Acetylene chlorid, that is, the, saturated chlorid of-acetylene more properly termed tetraclilorethane (l lcl Cl is a very desirable solvent which is not only non-inflammable other volatile inflziinn'iable solvents, suchas are used in i'ei'riovers. raising the flash point so that the remover is much more desirable under service conditions. Acetylene chlorid .is-also a good solvent for many waxes, resins and varnish gums and materially increases the solvent action of the remover. The acetylen'e tetrachlorid may be used in the form of chlorinated acetylene containing both the tetrachloi'id and dichlorid of acetylene, the dichlorid being apparently still. more efficaciou's insuppressing the inflammability of themore 'volatile inflammable ingredientsof the remover. Many alcoholic bodies may be used in'siich removers, including methyl,

v ethyl. propyl, biityl and'ainyl "a1cohols, es-

ecially in their cheaper commercial forms,

nclud ngdenatured and commercial allyl alcohols, and alcoholic derivatives, such-as ethyl. acetate and 'othegethers or esters; also other loosening finish'solvent material, that s, solvents having ajgenerally alcoholic :character-or action in removers, itch as the niethyl ethyl kctone a-fddflefilrabl'. .Qt-hei' 'finish solvents may alsobe incorporated in higher ketonesfizicluding adipin "stone, and

' removers of this character, such as terpineol andlight oil of wood tar; and also-solvents compr sing pin'enc,s1 1ch as light oil of cam lion, which is produced commercially in I arge quantities, the solvent powerof which may. be considerablyincreased by properly tractionating so Sto seem-e larger proportions of pinene in the solvents used.

Although not necessary in all cases, suitable stiffening material, preferably of a filmforining character, may be employed in these removers. including wood flour, fullers earth, vvhiting, infusorial earth and film-- forming stiffening material, such as paraffin. cert-sin and other waxy and soapy ma- I terials and gums, such as benzoin and Waxlike bodies produced by the combination of.

It is. of course, understood that in removers of this character only small proportions of the extremely volatile low boil ing point ingredients, such as methyl alcohol or acetone. should be used Where the minimum inflammability of the composition s tet rachlori d 30 parts, light oil ot'wood tar 70 parts. v.
